So just started year 12 but don’t start ext 2 classes until week 3. I’m on 12 units, but since ext 2 is 2units I can afford to drop 3 units of subjects. I have been strongly advised from head of math and careers advisor to keep the extra unit,eng ext, but I don’t see any point since I’m not taking it to the hsc. How risky is it to drop down to 10 units before ext 2 even starts?
